Dayu Electronics Vector Hydrophone: Single-Chip Microcomputer-Based Acoustic Particle Velocity Capture Technology

Accurate acquisition of underwater acoustic field information is the core foundation of marine monitoring, underwater acoustic detection, and engineering inspection. Dayu Electronics' independently developed vector hydrophone breaks through the limitation of traditional scalar hydrophones that can only measure sound pressure, enabling simultaneous capture of both scalar sound pressure and vector particle velocity information in underwater acoustic fields. Combined with a single-chip microcomputer system, it achieves efficient signal reception and processing, providing high-precision, high-reliability solutions for underwater acoustic applications.

The core advantage of the vector hydrophone lies in its precise capture of acoustic particle velocity. In underwater acoustic fields, particle velocity, as a vector physical quantity, contains information on both the direction and intensity of sound wave propagation, making it a key parameter for fully describing the acoustic field. Dayu Electronics' vector hydrophone employs advanced sensing chips and packaging processes, integrating three-axis sensing units to sensitively pick up particle velocity signals in three-dimensional space. It features a wide frequency response range, stable directivity, and high sensitivity, capable of meeting weak signal detection requirements in complex underwater environments.

To achieve real-time signal processing and application expansion, Dayu Electronics has built an integrated experimental system combining the vector hydrophone with a single-chip microcomputer. This system uses a low-power single-chip microcomputer as the core control unit. Through a high-precision signal acquisition module, the analog particle velocity signals captured by the vector hydrophone are converted into digital signals, which are then processed by built-in algorithms on the microcontroller for filtering, amplification, and analysis, effectively removing environmental noise interference and extracting valid particle velocity information. Experimental results show that the system can stably capture acoustic particle velocity at different frequencies and intensities, with high signal fidelity and fast response, offering advantages of miniaturization, low power consumption, and ease of integration.

Compared to traditional acoustic measurement solutions, Dayu Electronics' vector hydrophone paired with a single-chip microcomputer enables direct acquisition and real-time processing of vector acoustic field information, overcoming the limitations of scalar measurements and significantly improving the positioning accuracy and signal-to-noise ratio of underwater detection. This technology can be widely applied in marine resource exploration, underwater target localization, submarine pipeline monitoring, hydraulic engineering inspection, and other fields, providing core technical support for the miniaturization and intelligent development of underwater acoustic equipment.

Dayu Electronics remains deeply committed to the field of underwater acoustic sensing, persistently pursuing technological innovation and practical application. The research and development of the integrated vector hydrophone and single-chip microcomputer technology further perfects the company's underwater acoustic product portfolio. With reliable performance and convenient integration, it helps customers solve various underwater acoustic field measurement challenges and promotes the high-quality development of underwater monitoring technology.
